以下代码演示：
在mysql的循环语句中插入数据的例子，用到了mysql自定函数存储过程。
mysql> delimiter $$
mysql> CREATE PROCEDURE myFunction() //创建mysql存储过程
-> BEGIN
-> DECLARE i INT DEFAULT 1;
->
-> CREATE TEMPORARY TABLE ascii_chart
-> (ascii_code int, ascii_char CHAR(1));
->
-> WHILE (i<=128) DO
-> INSERT INTO ascii_chart VALUES(i,CHAR(i));
-> SET i=i+1;
-> END WHILE;
->
-> select * from ascii_chart;
->
-> drop table ascii_chart;
->
-> END$$
Query OK, 0 rows affected (0.00 sec)
mysql> delimiter ;
mysql> call myFunction(); //调用存储过程
